It features a cameo appearance from the original K-9 Mark I. Synopsis Whilst Starkey and Jorjie are trying to escape the police they take refuge in a large detached house, now the residence of reclusive scientist, Professor Gryffen and a robot dog, K-9 Mark I. After the ensuing battle with the Jixen, K-9 regenerates. Plot Two men arrive at the home and lab of Professor Alistair Gryffen with a case. After providing the case, containing a piece of technology from a "fallen angel" (a downed alien craft) they inform him that The Department wants a full report within 24 hours. Elsewhere, Starkey, a teenage boy, is near an outdoor public display board terminal and is hacking in to post a dissident message against the government. As he finishes Jorjie Turner, a teenage girl, arrives to yet again propose working together. Starkey refuses, but when the robot police arrive, the pair run off together. They find themselves in a back alley with police just around both ends. In desperation they try a number of doors until they find one unlocked. Once inside, they find the lab of Professor Gryffen. They hide in the shadows and watch as Gryffen begins an experiment with his STM (Space-Time Manipulator). As they prepare to leave Starkey kicks the power plug from the wall and the machines goes haywire. Instead of bringing back the professor's lost family, four Jixen warriors arrive through the STM's beam. As Gryffen and the two teens attempt to escape the creatures, Starkey is hit with their "Jixen slime" projectile secretions. As Jorjie and Gryffen turn to aid Starkey a fifth being comes through the beam. This time it's a dog like robot who tells the humans that his power is running low and that he must self-destruct in order to destroy the 4 creatures. As the team leaves the building, an explosion rocks the room and looking back they see the parts of the robot dog thrown across the floor. As they look around Starkey picks up an object that is still active. Shortly Darius, Gryffen's assistant arrives and sees the damage. Hearing the name "Stark Reality" (a name Starkey goes by) quietly calls the CCPCs (robot police) while Starkey apologizes to the
